To call this 4.53 metre high mount a mountain is a bit of a joke, but the name has stuck, thanks to a technicality in Japan's topographical mapping system. It's not even a natural feature, but a man made mound in the middle of Tempozan Park. At the time of its creation in 1831, it was 20 metres high. There is a memorial marking Emperor Meiji's first sea-borne military parade in 1876 next to the peak. Literally the only reason to come here is to be able ro say you climbed the peak of Japan's lowest mountain.
